I hope you don't mind me asking a related question here and not trying to hijack
this thread.

I have an old laptop which has no wireless and am using a Dlink GWL-G650
card - ath5k just crashes the kernel... so I installed madwifi 0.9.3.3 and
started wpa_supplicant up which works fine, and then did dhclient ath0 which
worked fine also. So now I have a lovely working connection - BUT ...

... within a minute I get a loud beep and messages on the screen such as:

I tried madwifi-ng from subversion and it essentially did the same. I used 
version 0.9.3.2 and it did the same. There are kernel parameters that can 
change the irq behaviour - and I have tried irqpoll which causes problems,
also noapic, nolapic, noirqdebug, irqfixup and various combinations and it
makes no difference.

Anyone give me any pointers to a workaround.
